As well, the optimum <br /> installation orientation of horizontal was met. The instruction manual for this meter as well as <br /> additional photos taken by Morada Produce during installation are attached as Appendix A. <br /> Sunnlemental Irrigation Flows <br /> 1 <br /> The supplemental irrigation flows are produced from a diesel-powered engine driving a enclosed <br /> type propeller vertical turbine pump (see Photo 3). Data supplied by the pump manufacturer (see <br /> Appendix B) indicates that at the given rating of the motor and with 304 feet of total depth head <br /> that the flow rate should be approximately 1800 gallons per minute (GPM). Since the engine is <br /> equipped with a digital hour gauge which is visible as the second gauge from the right top in Photo <br /> 4, reading this gauge at the beginning and end of pumping, taking the difference and multiplying <br /> through by the number of minutes in an hour and 1800 GPM should yield an reasonable estimate of <br /> total gallons of supplemental irrigation. <br /> Gallons pumped = #hrs x 60 min x 1 <br /> hr min <br /> ` l <br /> Hvdrocoolers <br /> The two primary packing lines at Morada Produce are for asparagus and cherries. Each of these <br /> packing lines are required by Food and Drug Administration regulations to apply chlorinated water <br /> to disinfect and chill packed food prior to shipping. These hydrocooler units have specific levels of <br /> chlorination which are measured and recorded by FMC controllers and are usually maintained at an <br /> approximate concentration of 60 parts per million (ppm) of free chlorine. Each packing line has <br /> two hydrocoolers whose drains are combined into one common line before metering. <br /> Aspargus H drocooler <br /> The two asparagus hydrocoolers are located outside the buildings and their drains are combined <br /> prior to metering. After metering they discharge to the main drain system (see Photo 5). The <br /> asparagus hydrocoolers are being metered with a SeaMetrics EX 80 Series electromagnetic flow <br /> sensor, model number EX82P-50, serial number 11041469. This type of meter lacks moving parts <br /> and is designed to be installed in piping from 1 to 8 inches in diameter, thus this meter is correctly <br /> sized for this application's 4 inch PVC pipe. The critical installation dimension of 10x upstream and <br /> 5x downstream for straight pipe have been met according to discussion with Lance Kagehiro of <br /> 1 Morada Produce. Vertical installation is implemented which is allowed by the manufactures <br /> instructions. This meter is connected to a counter that is attached via conduit to a power source. <br /> fJ <br />
